In case a long finger-bar and cutter are used the tension of the spring may be increased, so as to lift the outer shoe, by turning the bolt F and if it is wished to increase the lifting action at the inner end the saddle I may be moved stubbleward.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the gearing-carriage, coupling-frame, finger-bar, and the spring secured at one end to the main frame and the other end to the finger-bar attachments in tend to raise the outer end of the same, and the said spring connected between its ends to the coupling-frame, whereby a part of the stress of said spring is adapted to .tend to raise the said hinge-bar, substantially as described.

2. The combination of the main gearingcarriage, coupling-frame, finger-bar, and the spring secured to the main frame at one end and adjustably secured to the finger-bar at tachments, as by the chain or other suitable connection, in such a position as to tend to raise its outer end, and the said spring connected between its ends to the coupling-frame, whereby a part of its stress is adapted to tend to sustain the Weight of the latter and the inner end of the cutting apparatus, substantially as described.

3. The combination of the gearing-carriage, coupling-frame, finger-bar, and the spring secured at one end to the main frame and the other end to the finger-bar attachments in such a position as to tend to raise the outer end of the same, and the said spring adjustably connected at a point between its ends to the coupling-frame, whereby a part of the stress of said spring is adapted to tend in a greater or less degree, as required, to raise the said hinge-bar, substantially as described.
